The 48-year-old "Killing Them Softly" actor still feels betrayed and so he does not encourage his own kids - Maddox, 11, Pax, eight, Zahara, seven, Shiloh, six, and four-year-old twins Knox and Vivienne - to believe on him, reported E! online.
"I'm not a real big on the whole Santa thing. I thought it was a huge act of betrayal when I was a kid. I didn't like that. When I found out the truth, I was like, 'Why, why, why would you lie to me, why?'
"So what I tell them is some people believe it's Santa, and some people believe it's parents, and you get to believe whatever you want," he said.
While the 'Killing Them Softly' actor says he is soft when it comes to his daughters with fiancee Angelina Jolie, who is harder on the boys.
"I'm more of a disciplinarian with the boys. The girls do no wrong, of course. Mom's a little more equal in her dishing."
